Overview

Mouse monoclonal antibody against 6xHis polypeptide conjugated to allophycocyanin (APC). APC is a fluorescent light harvesting protein unique to cyanobacteria and red algae and a member of the phycobiliprotein family of direct fluorescent dyes. Surelight APC is a chemically and intramolecularly cross-linked form of a protein. It is produced using a proprietary manufacturing process to increase thermal stability while maintaining the fluorescent and spectral properties of native dye.

LANCE® (Lanthanide chelate excite) and LANCE® Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One molecule of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second molecule is labeled with an acceptor fluorophore [ULight™ dye, allophycocyanin (APC), etc.]. Upon excitation at 320 or 340 nm, energy can be transferred from the donor Europium chelate to the acceptor fluorophore if sufficiently close for FRET (~10 nm). This results in the emission of light at 665 nm (for ULight dye and APC).

Application Brief

Eight Limitations of ELISA and How to Overcome Them Using Alternative Technologies

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.

Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
